Title: MUD-GAS SEPARATOR APPARTUS AND METHODS
Abstract:
In one aspect, a mud-gas separator vessel defines an internal region in which a slurry is adapted to be collected. The slurry defines a fluid level. A sensor is adapted to measure the fluid level. An electronic controller is in communication with the sensor and is adapted to receive measurement data. A control valve is in communication with the controller and is adapted to control discharge of the slurry. The controller is adapted to automatically control the control valve based on the measurement data and thus actively control the fluid level using the control valve. In another aspect, a method is provided for automatically maintaining the fluid level to prevent vent gas carry under from the separator vessel. In another aspect, a kit is provided for actively controlling the fluid level. In another aspect, a method of retrofitting a mud-gas separator apparatus is provided.
